Well we still don’t know since this one is set between the events of Captain America: Civil War and Avengers: Infinity War. Scott Lang is now placed under house arrest after the events of Civil War.

The trailer of the movie promises great new
things with, finally a legitimate villain, Ghost, which though not a
very imaginative name but still better than what you find at the back of
your closet. Yellow jacket.. anyone?!?

It picks up with Scott played by Paul Rudd with
his daughter being all vulnerable and questioning his superhero
lifestyles, which sets up the stage beautifully for The wasp to be Yin to his
yang.

Wasp Played by Evangeline Lilly is a
perfect compliment to paul Ruuds goofy portrayal of Ant man, serious,
particular and knows what she is doing plus has a pair of wings which
she graciously never lets him forget.

The trailer re-introduces Scott's old partner
played by Micheal Pena, Michal Douglas playing Hank Pym and also in the
cast is Laurance Fisherbaurn as Bill Foster or Goliath from the comics.

The trailer already promises a marked improvement
from the previous one with the main attraction being the Character of
the main Antagonist, Ghost played by Hannah John-Kamen. Marvel realized
sometime back that the key to a successful movie is an engaging villain
which actually has a screen presence and not just there as a punching
bag with a bunch of one liners. An interesting point over here is that they have
changed the sex of Ghost over here as in comics it was a man, but hey it
still looks kick ass and will give the heroes a run for their money.

Lastly looks like they have finally gotten a hang
of how to properly use both the shrinking and expansion powers of ant
man and wasp for a proper fight scene choreography and thankfully we
will be spared the Thomas engine climax fight from last time.

Overall with a gap between marvel film schedule
this definitely looks like an enticing desert served by Disney and co. to
cap off their superhero summer and something not to be missed at all.
